Finally came in and got around to installing it a couple weeks ago. Installation was a breeze. I love the intake. The GC finally sounds more like a turbo diesel. The intake noise is cool, but not obnoxious. It can be drowned out fairly easily with the radio volume.
Sound is cool...so...how does it run? I would love to know what your before/after map pressures are at idle. Mine idles at -2.4 psi of boost with a stock airbox.
I'm a little leary of using a less efficient filter. The stock paper filters have been shown to do a better job of filtering than oiled cotton gauze. Maybe AFE uses something better than the junk K&N sells?
Also, I wonder why AFE didn't create a box that connects to the CAI intake in the front instead of pulling hot air like they do?
I would be worried about water ingestion.
A diesel needs to have a snorkel to guard against it and needs to get fresh air unpolluted by dust or dirt
From the photo you get lots of mud dust, water etc.
Good luck but I am waiting for a seal system snorkel under development in Australia
If I get water up that high, I have more than just water ingestion to worry about. A splash of water or mud isn't going to hurt anything. I've been running open element filters for 15 years and have never had hydrolock. That said, I may buy a pre-filter element, just to help keep the filter cleaner, longer.
For a completely stock air box at idle I reviewed my boost psi and found some surprising variation from run to run...
with a minimum of -2.32psi then -2.22 psi and -1.88psi.. all quite similar ambient conditions...
So it may be difficult to see any changes with less restriction on the induction.

I'll watch mine to see if its as variable as yours. I read somewhere that there is a throttle plate of some type on modern diesels...depending on sensor location, this could cause a variable vacuum at idle.
I plan on having this put on with before/after dyno...there's a tuning shop right up the road from me, and they want to do some tuning and maybe exhaust. They do all Corsa's dyno tuning during R&D, and are interested in doing intake/exhaust/tune and look at the turbo. I trust them, I know several guys who work there. In fact they had done an Aventador tune/exhaust and had to have a Lambo engineer come from Italy to watch them. Then the guy had them put it back to stock and bought a Mclaren P1. $50k for tune/exhaust and back to stock. Even with the DPF, I think we could see some modest gains in MPG's with the right air improvement
The Bluespark tuner on the highest setting is (if they aren't exaggerating at 317 hp) over 100hp per liter...that's pretty much "beast mode" in the stock form of this little motor. My 7.3 liter diesel would make 771 HP at that rate. It doesn't and it has exhaust, intake, injectors, and turbo upgrades.
I suspect hardware would need upgrading to support much over the current gains that are possible. I think the fuel system is the limiting factor...maybe the turbo too.
I hav a cummins and help develop the efi for the 5.9s 06-07.
With efi live its not about dyno numbers which 99% of the tuner companies advertise. Its about usable power in the real world or should i say driving/driver specific. U can tune it based on your life style and environment vs a generic program. Which before was more than enough for me till i discovered efi.
Beast aren't judged by peak HP only, of course. The Bluespark Pro already hits the torque limit spec of the ZF tranny...and comes on strong at low rpm. I'm not sure how an ECU tune would "drive" better if a Bluespark tuner already drives great.
One thing I'd like out of my Eco is some turbo whistle...I pulled the silencer ring out of the Holset on my Cummins, and it whistles quite nicely now. Open element / cone filters on my 2.2 turbo Dodges get a similar result. Anyone been able to (or even tried to) get some whistle out of the VM?
I've had the AFE intake installed for about a week. Went with the dry filter but will be getting a pre-filter as well for off-road use.
I've noticed better throttle response (turbo spools faster) and have enjoyed the sound. Its not abnoxious and is easily dealt with via closed windows. Any power gains can't immediately be felt but thats fine with me. The throttle response was what I was after.
Can't speak to fuel economy yet...I don't suspect much though.
Overall, I am very happy with it. Very easy install and it's got the cool factor.
ive been looking to get one of these, but for $5XX does it give any improvements over the stock one eg. fuel consumption, proven throttle response? Ive replaced them on nearly all my cars but the throttle response is more of a bum placebo effect rather than real effects.
im just asking as ive never spent this much for an intake! im not fussed about the sound, i dunno i might be getting a lil old. I prefer to be quiet nowadays..
Paying 500 or even 250 to have your engine breath dirtier air isn't worth the gains to me if there are any. Its just a tube, less effective air filter, and a heatshield. Why they don't offer an improved airbox that takes advantage of the factory cold air inlet baffles me....
The AFE intake does utilize the factory cold air inlet. The top of the box does also seal / touch the hood which should prevent too much bay air from entering. The stock tube was very restrictive with all the ribs and the baffle. You can see they designed it to eliminate sound.
Check these out. Kind of hard to see but I can confirm the inlet is utilized. Regardless, people buy what they want for whatever reason. I'm happy with it.
Thanks for the info. If it seals on all sides with the front corner, that's a big plus. Is there additional room for a larger paper filter? The cotton gauze filter's poor filtration is my only reservation.
With forced induction engines I'm always scared of just adding something that alters fuel/air ratio with worries of leaning out. Not sure if it is such a problem with a modern turbo diesel. Less so with a drop in filter.
Diesels don't have lean and rich mixture issues like a gasser. Too rich makes excessive smoke (fills the dpf quicker), too lean reduces power. Neither is destructive to the motor within very broad limits. The A/F varies on diesels based on load and isn't constant.
that would be sweet! would be funny to have some diesels beating up on the SRTs. the wife said i cant play with this diesel's engine. think it freaked her out seeing the top end of the truck in pieces.
in regards to the intake, the biggest cork in the engine is on the hot side, so intake will change nothing but the sound.
still deciding between the diesel or hemi for my 15 summit
